An experiment set-up for analysis of lateralization judgments of binaural stimuli

The aim of this work is to present a physical implementation of a noninvasive methodology to analyze the directional sensitivity of human auditory system. A computer controlled experiment set-up has been designed and developed to study the behavior of human beings under the presentation of interaural time delays and interaural amplitude differences for several sensation levels. Numerous lateralization judgments are accomplished in order to investigate the transduction mechanism which allows deciding in which side of listener medial plane the source of binaural acoustic stimuli is located.
